EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,747, dated April26, 1887.

Application filed May 19, 1886.

To all whom, it may concern:

Be 1t known that I, EMIL CoRNnLY, a resident of Paris, in the Republicof France, have. lnvented anew and useful Improvement in Eur'broideling-lldachines,` which-is fully set forth in the followingspecification.

In Letters Patent of the United States No. 311,644, of February 3, 1885,I have described and claimed a new method of fixing cords or braids totextile fabrics by winding a thread around said cord and around thestitch of a sewing or embroidering machine. The method explained in saidLetters Patent can equally be applied when stringed beads are to beiixed to textile fabrics; but inasmuch as a string of beads passes withgreat difficulty through the machine on account of its asperities, itrequires special mechanical devices for obtaining a good result. Theywill be understood by reference to the following description and theaccompanying drawings.

Figure'I represents an elevation of the head of an embroideringmachine.Figs. II, III, and IV represent detached views, hereinafter to bereferred to.

As the general construction and operation of the machines to whichthepresent invention is or may be applied are well understood, and are,moreover, fully described in Letters Patent heretofore granted to me-forinstance, in Letters Patent No. 228,445, dated June 8, 1880, and262,742, dated August 15, 1882-it will only be necessary to describeherein the particularparts or improvements which constitute the presentinvention.

I employ a string of beads 011 which each bead is fixed by means of asecond thread in such manner that there will remain a small spacebetween each two following beads. As such strings of beads are alreadymanufactured for weaving purposes, they can be obtained easily andcheaply.

The same as in Letters Patent N o. 311,644,

` A represents the cloth; B, the needle-hook; C,

the nipple; a, the cording-guide; D, the nipple-tube; E, the needle-bar;Ghthe rotating thread-carrier; H, the string of beads to be xed to thematerial.

I employ a hollow or tubular needle-bar, E, which is provided at its topwith a funnel, b, into which the string of beads can glide withouthinderance, and through which it can descend through the entire lengthdownward and along the needle B, and thence through the cording-guide c,and downward to lthe cloth, to which it is fixed bythe thread, which iswound by the thread-carrier G around the string and around theloop-stitch of the machine, as explained in Letters Patent 311,644.

To insure perfect work, it will be necessary, when working on very thinmaterial, to employ an automatic feed device to supply a certain lengthof stringed beads to the material. This feeding device may be composedof two small cylinders, d h, of indiarubber, or of 6 5 othermaterial,which turn within a small frame of the nipple-tube D. They areconnected together by means of two pinions, m o, Fig. IV, and thecylinder d is provided with a rack, s, which, when the nipple-tube Drises, strikes against a small spring-pawl, a, which is secured to thefixed tube g, within which the nipple-tube operates. The string of beadsis wound around the cylinder h, and, passing between the two cylindershand d, descends to the cloth through the guide a. As the nipple-tuberises at each stitch the cylinders d and h turn and feed a certainlength of string to the work. The thread, as it passes from the spool q,through the guide r, and through the thread-carrier Gr, is wound in sucha manner around the string of beads that it will always place itselfwithin the space which exists between two beads, and it will thereforenot be visible. The hollow needle-bar E is secured to the tube T bymeans of a set-screw, o, and the tube T receives its verticalreciprocating motion for operating the needle-bar E by the well-knownmeans employed on sewing and embroidering machines.

The ap paratus,consisting of the parts V, X, Y, and Z, h', 7c, o, p, andn, is the same as the one for which application for Letters Patent hasbeen made by me, (No. 156,527, filed February 20, 1885,) and whichserves to tighten each loop of the chain-stitch when the needlecommences its downward movement. This apparatus is equally effective formaking beadwork.

It is evident that bead-feeding appliances of 10o various constructionsmay be made instead of the feed-rollers above described, and I thereAest, `and. Fig. iii in its highest, position.

A similar bead-feeding device can also be applied at the top of theneedle-bar, or at its funnel-shaped mouth, to supply the desired lengthof the bead-string to the work, which in many cases is necessary, as theordinary tension on spools of sewing-machines does not work effectivelyon the spool on which the bead-string is wound.

l. In a sewing or enibroidering machine of the character described, thecombinatiomwith the stitch-forming mechanism, of the hollow needle-barprovided with a funnelshaped month, substantially as and for the purposeset forth.

2. The combinaliomwith the stitch-forming devices and the rotatingcarrier for wrapping a second thread around the sewing-thread, of thehollow needle-bar having a funnel at its upper end, and the 4guide a,for directing a cord or string of beads to the fabric, substantially asdescribed.

3. The combination,with the stitch-forming devices and rotary carrierfor Wi nding a second lthread around, the sewing-thread and around acord or string of beads, of automatic feeding mechanism for supplying acertain length of cord or string to the work, substantially asdescribed.

4. `The combinatiomwith the reeiprocatory needle-bar, of thefeed-rollers carried thereby or connected therewith, and means, asspecied, for rotating said rollers step by step at each reciprocation ofthe needle-bar, substantially as described.

5. The combination of the hollow reciproca: tory needle-bar, the feed-rollers geared together'and carried by said needle-bar, a rack orratchet on one of said rollers, and a pawl carried by a part of themachine, stationary with respect to said needle-bar and arranged to actupon said rack or ratchet at each reciprocation of said bar, therebyrotating said feedrollers, substantially as described.

In testimony whereof I have signed lthis specification in the presenceof two subscribing witnesses.

- EMIL CORNELY.
